cGiiLvANIzING SHEET `iiiiazsriu.. y

It is Well know'li'ow sheet metal is galvam ized vertically in baths; i'Ilither-toforcarrying,r out this processseparators were necessarybetween the anodes and cathodes. has,` besides other disadvantages ,thatpai'ts of the anodes `are covered By pressing the points oftlieseparators on Ithe cathodcs there are `ontlie Whole siiriace places`which are not galvanized,fso that onacci-)nntxol forgetting the'necessary displacing` of Vthe sheet' n ietal,V a nui'ber of refnsegoodsnireitiirncd out. i The points oi" the. 'known separators? generallybreak 'oif -oi become defectivev which .makes this kindoi working veryexpensive.`

The present invention relates to `adiwice` for galvani'zing sheet-metal'on 'the whole su r face without the'nseof separators, so that/"thecathodcs and anodes are lree over their whole surface which fortheaiiodescauscs aneqnal displacing and entire useandthe cathodes areequally galvanized on both sides. In

order to inake this possible angular pieces et noncondiicting materialsuch as glass, poi'- celain or eai't'henware are placcd-on the woodenbeams `which lieacross the bottom oi" the bath. supported in cuttings inthe angular pieces oi glass or the like and atthe top betweentwo glasspins ixed to a movable wooden nni. In this manner theicnthodcs are heldin a vertical position. Vilhe cathodes which` can be ol any uneven shapecan coiwcniently be held with 'thc hands nntil'tlw glasspin's Iareplaced in positimi to hold them. 'ilhe'twb anodcs are screwed to`wooden`l`ranics rand can separately be taken ont. '()ne ol' the frameswith one anode rests at the bottom i oi' the `wooden beains, andhcld ina-vertical position at the top by'two wooden holder 'lhe'lranie withthcsecond anode is pivoted to the `wooden beams and'lieldin a verticalposition by two woodenholdersatthe-top;
